' a simply constructed and efficient device of this character in whichthe :parts, while simple, will reliably and firmly hold the,

scythe blade in connection with its snathe or "handle, and which is soconstructed as to permit the blade to be readily removed when founddesirable to do so.

With the foregoing and other objects in View, which will appear as thedescription roceeds, the invention resides in the com ination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings:-

. Figure 1 represents a side elevation of the blade and of a scythe, thehandle being broken off for convenience inill'ustration and with partsbroken out,

Fig. 2 isa similar view taken from the opposite side of the scythe,'

Fig. 3 is a horizontal section taken 011 the line 33 of Fig. 1,

Fig. 4 is a longitudinal section taken on the lined- 1 of Fig.2, and

Fi 5 is a plan view of one of the rings showing the wrench for use inconnection therewith in operative position with parts broken out.

In the embodiment illustrated a scythe handle or snathe H is shownhaving one side thereof flattened as shown at h and which carries ablade B of ordinary construction having the usual shank S and which isdesigned to be secured to the handle H by a fastener presently to bedescribed which constitutes this invention. a

The shank S has an inturned finger s at its free end which is designedto enter an aperture in the handle H through an open- Patented ll eb as,rare.

ing 0 formed in the ferrule presently to be described.

The fastener constituting this invention comprises a tapered ferrule 1shaped to engage the lower end of the handlejfll having a fiat innerside wall2 which 'isdesigned to fit over the flat face it of said handleand thereby prevent all possibility of the ferrule turning on the handleand which is further secured to the handle by means of a bolt 3 whichextends transversely through an apertured lugjt carried by the upper endof the ferrule and transversely through the handle as is shown clearlyin Figs. 1, 2, and 42. This ferrule 1 is externally threaded as shownclearly at 5 in Figs. 1,2 and l and is split longitudinally throughoutits length as shown at 6 to permit it to closely engage the handle whenvthe clamping rings 10 and 11 are placed in operative position. aswill-be presently described. This ferrule 1 has a recess 7 arrangedlongitudinally in its'outer' face on the flattened portion thereof asisshown clearly in Fig. 3 and which forms a seat for the shank S of thescythe blade when the parts are assembled as is shown clearly in Fig. 3.

The ferrule retaining and clamping rings orb-ands 10 and 11 areinternally threaded to fit the threads of the ferrule 1 and similarthreads 8 which are carried by the outer face of shank S, said threads 8being so formed as to register with the threads 5 of the ferrule whenthe parts are assembled and form a continuation of said threads. Theserings are also provided each-with a radially eX-, tending stud 9 whichis designed to be engaged by a wrench '12 having an aperture 13 in oneend adapted to fit over said stud to facilitate the screwing andunscrewing of the rings. This wrench has a handle 14 projectinglongitudinally therefrom to afford ample leverage for operating therings, said handle being shown broken off in Fig. 5 for convenience inillustration.

From the above description it will be obvious that in the assembling ofthe parts of this device, the ferrule 1 is first placed on the lower endof handle H and secured thereto by the bolt 3, The shank S then has itsinturned finger or spur s at its free end engaged with the aperture 0 inthe ferrule and the corresponding opening in the handle H as is shownclearly in Fig. 4. The rings 10 and 11 are. then screwed down over theferrule and shank S thereby forcing said ferrule into tight clampingengagement with the shank and the handle so that the shank is securelyheld against all possibility of its this connection.

When it is desired to remove the blade for any reason the ringsare firstremoved by enconnection with the accompanying drawings,

the advantages of the construction and of the method of operationwill'be readily apparent to those skilled in the art to which theinvention appertains and while I have described the principleofoperation of the invention together with the device which I now considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such changes may bemade as are within the scope of the claimed invention.

I claim:

1. The combination with a scythe handle,

a ferrule mounted on said handle, cooperating means carried by saidhandle and fer rule for holding the ferrule against turning on thehandle, a seat extending longitudinally of said ferrule, threads formedon the exterior of the ferrule, a blade having a turning, the two ringsoperating to insure shank adapted to fit in said seat and PTO: videdwith threads on its outer face adapted to register with the threads onthe ferrule, and a clamping band having interior threads for engagingthe threads of the ferrule and shank whereby they are locked to eachother and to the handle.

2. The combinationwith a'scythe handle having one face flattened at itslower end, a tapered ferrule having a fiat inner face to fit on saidhandle and whereby it'is held against turning relatively thereto, a seatextending longitudinally of said ferrule on its outer face, said ferrulebeing split from end to end with the edges of said split portionnormally spaced apart, a blade having a shank adapted to fit in saidseat, and a clamping band for engaging said ferrule and shank forlocking them together.

3. A scythe blade fastener comprisin a longitudinally split exteriorlythreaded ferrule having a seat extending longitudinally of its outerface to receive the shank of a blade, clamping bands interiorly threadedto fit the threads of said ferrule, and means carried by said bands tofacilitate the turning of the bands on the ferrule.

4. A scythe blade fastener comprisin a longitudinally split exteriorlythreaded ferrule having a seat extending longitudinally of its outerface to receive the shank of a blade, clamping bands interiorly threadedto fit the threads of said ferrule, and studs extending radially fromsaid bands to facilitate the turning of the bands on the ferrule.

In testimony whereof I afiix my signature in presence of two witnesses.
